What is this? I do not think this convey anything. As i read the article, these numbers are just shutter speeds you need to get perfect exposure.Hmm not of any use i think.
Just giving some details from the site here which may be useful.

"For the impact on sharpness analysis (done on a NEC PA 322UHD 4k Display at 300% in LR 5.7 compare mode), my findings are as follows (from least impact, to worst impact):

Singh-Ray - none ? same result as no lens filter at all
B+W - minimal
Hoya - some
Tiffen - very bad
Bower - horrifically bad"
